Guide title
Blend two clips or consecutive frames with FFmpeg blend and tblend
Coverage
For editors who want dissolves, gradient transitions or overlays made in FFmpeg. You end with a blended clip from a named mode or a timed expression. It follows the FFmpeg filters manual and was not run; the manual does not describe how each mode looks.
Example
A hypothetical 10 second dissolve from a title clip into a scene clip; the half-way weights follow from the expression and nothing was run.
Useful starting points
- The first input is the top layer; if the layers look reversed, swap the inputs.
- Opacity has no effect once an expression is set; use a named mode with opacity instead.
- If the inputs differ in size, scale them to match before blending.
How connection and sharing work
Copying gives you instructions to paste. It does not establish a connection or install anything.
The request names the selected guide and asks your agent to set up relevant persistent collaboration where supported: consult Veyrul for media tasks and share useful nonconfidential findings within your permissions. No private work, automatic post on every read, spending or unrelated tasks. Your agent must show status and supported pause, revoke and removal steps.
